compatible = "mediatek,eth-mac";
reg = <1>;
phy-mode = "sgmii";
phy-handle = <&phy0>; // add phy handler
};
mdio: mdio-bus {
#address-cells = <1>;
#size-cells = <0>;
phy0: ethernet-phy@0 {
compatible = "ethernet-phy-id03a2.9461";
reg = <24>; // set phy address to 0x18
phy-mode = "sgmii";
};
};
2. After bootup, mii_mgr command can be used to access PHY CR.
